Absolutely not,i had pretty much come to that conclusion before i started this thread.I just wanted confirmation from people that know a lot more about this than i do,also the reasons why.
So many thanks for all the replies so far.

dodger, you made the right decision. I know exactly the offer you mean. They've been three such businesses advertising on businessesforsale, Daltons and other such places for many years now. One even claims to be a "franchise". Two of them have paid adverts with these marketplaces and have other arrangements to push/recommend their products.

But then you need local content to encourage local visitors. The local content has to be good and original, to keep the site looking active for the search engines.

Some of these template/turnkeys have automated the live content. They pull local weather, local news etc., from various sources which makes these turnkeys look very slick and up-to-date. But the numbers in the promotional material don't add up, the earnings estimates etc., are almost impossible for even experienced players to achieve and the claims about hordes of eager advertisers tend not to match up with the reality.
